Monitor won't wake up when coming back from sleep (Windows 7)

Anonymous

I recently upgraded my Dell Dimension desktop to Windows 7. In order to do so, I had to install a new grapchis card (NVIDIA GeForce).

I set the PC to sleep after a period of time. When I go to move the mouse and wake the computer back up, the PC itself seems to respond, but the monitor never comes back from sleep. I have no choice but to reboot to get the monitor back.

Any suggestions?

A Universal fix would be ideal but - ASUS appears in 14 out of the 16 pages in this thread!!! Not saying everybody having this problem has an ASUS motherboard but if they do, and it seems a high percentage of people do, then they need todisable the PLL Overvoltage in their BIOS!!

IT ACTUALLY WORKS! Not just a workaround, my Computer AND Monitor now both wake from sleep by simply moving the mouse!

Also, obviously only people who have this problem are going to come here. If this is a wide-spread Windows 7 problem, then what about all the complaints large companies like HP Compaq and DELL etc would receive when their customers have the same problem? If they received many complaints and being that they have a much bigger voice than us they would simply demand Microsoft fix it. I also have a TOSHIBA laptop running windows 7 and it sleeps and wakes just fine.

So if anybody who has friends or family who own a 2011 Dell, Acer or HP etc that came out brand new, factory loaded with Windows 7 please ask them if they have this issue or not. (These companies may have had this problem initially but I would imagine it would be fixed by now??!!)

A lot of people who have this problem also seem to have a separate Video Card (I have a Sapphire Radeon HD 6870 which of course the monitor is connected to) Do any people who are using integrated graphics also have this problem such as people with an H67 mobo?

I am curious as to what percentage of Windows 7 users have this problem. We may find we are in the 1% bracket and 99% of Windows 7 users don't have this problem. It may just be incompatibility of Windows 7 with either our hardware or settings.

In my case disabling PLL Overvoltage works! :-)

I have the same problem with Win7-64 and a dual monitor setup. The secondary monitor comes back on, but the primary monitor, which has my desktop, stays off. I loaded the latest drivers, no joy. Played with the power settings. Nothing. I did, however, discover a simple workaround, but not a solution. When I move the mouse to wake it up, the secondary monitor then turns on. I hit CTL-Alt-Del and the primary monitor comes back on and shows the Task Manager. I then hit "cancel" and the monitor stays on. Not great, but it is a workaround.

The funny part is that when it goes to sleep after 30 minutes, and I move the mouse, the primary monitor comes back on as you would expect. Its the 10 minute to 30 minute window that is problematic.

Hey there,

Just wanted to let you guys know that I managed to fix my similar issue.

My problem was that when putting my laptop to sleep or hibernation for more than a few minutes, the screen wouldn't turn back on when waking the laptop back up. I could tell that the computer was still running and it was isolated just to the monitor or video card. I'm running Windows 7 Professional on an HP Envy 15 laptop.

My work-around originally was to press the power button to put the laptop back into sleep. Then press it a second time to wake it back up. This would work, but was inconvenient.

To fix this, I first removed the extra RAM I bought for the laptop. That didn't work. BTW, I later found out that despite buying the same speed and type of memory my laptop uses, it wasn't the 'correct' one for my laptop (which is new to me. Wasn't aware that they become even MORE specific than that). I then went to ATI's website. They just released a new driver back in August. I updated to that driver, and my issue is now fixed.

For the rest of you still struggling with this issue, I would recommend checking on your video card company's website for theNEWEST drivers. I originally already had the newest, but it was those drivers causing the issue. The drivers I have now fixed them. If yours doesn't work, I would suggest rolling back to an older version. Hope this helps!

Hello

I have had the problem to and fro when putting my computer to sleep.

To me it would appear that several different reasons can be the cause but I found one very obvious reason today:

I connected to the computer from my laptop using Remote Desktop Connection and checked the Device Manager, only to see that the Monitor was not present in the list.

So I simply went into the Action menu and choose "Scan for new hardware changes" and VOILÁ - the monitor lit up showing the Windows login screen and everything was hunky dory again!

Now, I don't think this is an acceptable "work-around" but it might very well be the issue here, that the monitor drivers are temporarily unlocated for whatever reason upon wakeup.

Microsoft should dig a bit deeper into this, I think, and you people could attempt using Remote Desktop Connection to see if this would resolve your problem.
